i am trying to generate / change the macro placeholder dynamically after the user entered some value in the edit page.
It should work exactly like e.g. the status macro (example below).

The tutorial (https://developer.atlassian.com/server/confluence/providing-an-image-as-a-macro-placeholder-in-the-editor/) only shows how some predefined pictures can be displayed.
But i need to create the image depending on the user input.
The behaviour should be like in this Status macro:
